Python’s Built-in Functions – Real Python

The built-in locals() function returns a dictionary representing the current local symbol table, which includes variable names as keys and their currently bound references as values. This function is useful for inspecting the state of the local scope within a function or other local contexts:

• The built-in locals() function doesn’t take any arguments.

• Returns a dictionary representing the current local symbol table with variable names as keys and their corresponding values.

With a function to display local variables:

When called in the global scope:

The most common use cases for the locals() function include:

• Debugging to inspect variables and their values within a function
• Dynamically accessing and manipulating local variables, although direct modifications to the dictionary should be avoided
• Understanding the scope and lifetime of variables within functions

You might want to log the state of local variables for debugging purposes when a function fails:

In this example, the locals() function provides a snapshot of the local variables when an error occurs, which can be invaluable for debugging.

Tutorial

In this tutorial, you'll learn about Python namespaces, the structures that store and organize the symbolic names during the execution of a Python program. You'll learn when namespaces are created, how they're implemented, and how they support variable scope.
